Specification of Letters Patent.

Patented June 16, 1908.

Application filed January 20, 1908. Serial No. 411,826.

To all whom it may concern;

Be it known that I, CARL EINAR IIAN- mm, a citizen, of the United States, residing at Cincinnati, in the-county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Tongs; and I do hereby declare the following to be a full, clear, and exact descri .tion of the invention, such as will enable ot iers skilled in the art to which it appertains to make and use the same. 1

My invention relates to new and useful improvements in tongs and more particularly to that class adapted to be used for removing the base of incandescent bulbs from their sockets and my object is to provide a device of this class whereby the base of the bulb,

may be positively and quickly removed from its socket.

A further object is to rovide means for insulating the handles of t e tongs, whereby the base may be removed from its socket, while charged with electricity.

A still further object is to provide a cushioning device for the handles of the tongs and a still further object is to provide means at the u per ends of the tongs adapted to break the g ass remaining in the base and positively engage the metal portion-of the base.

Other objects and advantages will be here inafter referred to and more particularly polntedout in the claims.

In the accompanying drawings which are made a part of this application, Figure 1 is a perspective view showing my improved tongs applied to use. Fig. 2 is an enlarged elevation of the tongs showing portions of the handles thereon broken awa Fig. 3 is'a sectional view as seen on line 3-3, Fig. 2. Fig. 4 is an enlarged view of the grippin ends of the tongs, and, Fig. 5 is a sectlona view through one of the handles as seen on line 55, Fig. 2. 1

Referring to the drawings in which similar reference numerals designate corresponding arts throughout the several views, 1 and 2 indicate the sections of my improved tongs, which are pivotally secured together by introducing an interiorly threaded socket 3 through openings in the sections 1 and 2 and entering a threaded stem 4 into the socket 3, said socket and stem having heads '5 and 6, respectively, extending across which are channels 7 and 8 to receive the pointed end of a screw driver, or the like, by which means the socket and stem are tightened orloosened.

The sections 1 and 2 above their pivot point, are formed into jaws 9 and-10, respectively, the upper ends of said jaws having outwardly curved terminals 11 and 12, each of which are provided with a substantially V-shaped notch 13 and 14, said notches forming cutting edges 15 and 16, at each edge of the terminal, for a purpose to be herein described. That portion of the sections 1 and 2 below their pivot point, is formed into han-- dles 17 and 18, respectively, which are surrounded by anysuitable form of insulating material 19, preferably rubber and onthe outer faces of the insulating material, are formed cushions 20, which cushions preferably consist of hollow members filled with air. The jaws 9 and 10 are normally held in their closed position by introducing a spring 21 between the handles 17 and 18, said spring being preferably coiled and held in position between the handles, by introducing theends of the spring over studs 22 on the inner faces of the handles, said spring exerting outward pressure on said handle at all times.

This instrument is adapted more particularlyto be used in cases where the bulb has become broken, for removing the base of the bulb from the socket and, to this end, the socket 23, containing the base 24, is grasped in one hand and the tongs in the other hand, the jaws 9 and 10 being then introduced into the opening in the base 24 and inward pressure directed on the handles 17 and 18, which will force the cutting edges of the terminals 11 and 12 into engagement with that portion of the bulb 25 remainin in the base and destroy the same, so that by a continued pressure on the handles, the\terminals will be directed into engagement with the inner face of the Wall of the base 24, when by holding the socket firmly, the base may be removed therefrom by rotating the'tongs and it will be readily seenthat by providing the insulation on the handles of the tongs, the base may be removed while charged with electricity without communicating the charge to the person using the tongs.

This instrument is-expressly applicable in connection with display signs, or where a number of bulbs are energized from the same feed wire, in view of the fact that any one of the bases may be removed from its respective socket without affecting the use of the remainder of the lights and by forming the free ends of the jaws with outwardly curved terminals and providing cutting edges thereon,

the base 24 will be firmly engaged when pressure is directed on the handles of the instrument and caused to leave its socket when the instrument 'isrotated.

What I claim is:

An instrument of the class described comprising a pair of sections pivoted together and terminating at one end in bowed jaws and at the opposite end in handles, said bowed jaws terminating in outwardly curved portions, the end face of each curved portion having a V-shaped notch therein, the walls of the notch merging with the side wallsvof the curved portion, said notch being of such depth as to terminate adjacent the base of 15 the curved portion.

I In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
